Verifying Update Failure (iOS 10.3.3)

My iPhone 6 on iOS 10.2.1 hasn't been able to update over-the-air since 10.2.1. Every time, I download the new update, go to install it (OTA), and it hangs on Verifying Update, or eventually says "Unable to Install Update. An error has occurred installing iOS 10.3.3."

Does anyone know why this may happen? Is it a lack of needed free space? Does it have anything to do with 2-factor verification on our Apple account? Does it not work on wi-fi? Does it not normally work on LTE?

I've deleted the update multiple times and re downloaded, then tried to reinstall. I've made sure I have 4 GB of free space. I've disabled 2-factor verification on my account. And I've tried both wi-fi and through my cellular data.

The only thing I've ever found that addresses this problem is when people suggest to update via iTunes. This doesn't explain why these Verification Updates don't verify correctly, nor does this solve the problem for someone who uses an iDevice independently from iTunes.

iTunes is a solid work-around, but I'd love to know how to fix the problem so it will verify an OTA update instead of constantly being told to do it another way. If OTA updates are still something Apple supports, then they should have a fix/solution to the OTA updates not working, shouldn't they? And not just a work-around, suggesting to do it a different way, which requires the customer own another piece of computing hardware. Does anyone know how to fix a "Verifying Update" or "Unable to Install Update" failure?!? Or does everyone not know, including Apple's tech employees?!?

I tried all of the other suggestions found on other threads did not work for me.

If you are/were part of the iOS beta program delete the beta profile then shutdown/restart your phone.

A sign this is the problem is that in Settings>About>Version = 10.3.3 and the update is also showing 10.3.3

This is what I did to fix:

Settings>Storage & iCloud Usage>Manage Storage>iOS 10.3.3>Delete Update

Settings>General>Device Management>Apple iOS beta>Delete

Power cycle phone

Settings>General>Update>(New update >10.3.3 is available)

If you mean resetting the network settings, I think it will forget all of the saved passwords for secure wi-fi connections. Every time I've done it, I've had to log in to each wi-fi network I use for the first time.

Apple makes it so easy to back up your phone every night that there are very few good reasons not to.

1) Make sure you're signed into iCloud and have back up enabled.

2) Plug your phone in to a power source. Added advantage: your phone will be fully charged and ready to go in the morning.

3) Make sure your connected to WiFi.

4) Lock the screen.

If you do this, you'll almost never be at risk of losing more than a day's worth of data.

Lost all pictures/videos, only have some contacts while others are gone, lost all notes yet reminders are in tact. So far that's all I have discovered since downloading the update yesterday 8/11/17. Phone locked up on the iTunes connect screen, had to download iTunes on my work PC to connect. Once I connected the phone to it, I chose Update (not Restore), received a message if phone could not Update it would need to Restore. I saw a button for Restore but it was gray. I guess iTunes decided to just Restore without allowing me to push the Restore or opt out (I would have taken it to an Apple Store instead of Restore). Phone came back on but needed an authentication code and the only option was to send the code to my phone. Since the phone was locked and needed the code, I couldn't retrieve the code sent to m phone (******), after attempting to send the code 3 or 4 times to the phone, the phone automatically unlocked and I was able to get in only to discover no pictures, notes, only some contacts (old and recent while some older ones than the recent one disappeared). Needless to say I think I will be switching to andriod after 7+ years using Apple devices.

I had the same problem. I tried about 10 different things that didn't work but finally got it to work by just turning my wifi off (insert major eye roll here). Super annoying but glad I finally got it to work.

I had this same issue. I went under Settings and Reset All Settings. Once the phone came back on it automatically started installing the update.

The same thing is happening with my new watch and my iPhone 6. I'm due for an upgrade but until I get my new phone my watch is basically useless since I can't update my iPhone!!

After resetting all settings did it remove anything from your phone like photos or Anything that hasn't been backed up?

I downloaded 10.3.3 and found after rebooting "No Mail box aka icon or configuration" on the phone? Apple suggested to go too the Apps Store and download another.

Which one?

Unfortunately, I don't know what that means. Do you have your mail synced with iCloud Drive?

Hi, after updating I can't use my message. it's just stack. I have tried to restart and use it again. same problems still facing and phone getting warmer too much which never happened.

Jul 29, 2017 6:47 AM in response to asmith198

Yah well I did that three times, I don't know if it has to do with my phone being jail broken and then un-jailbroken, but that doesn't work for me.

Have you reviewed your crash logs under Privacy? Connecting to the Console app on your computer with a USB might very well tell you what's wrong.
